A bug, unless I'm mistaken

A bug, unless I'm mistaken

[Michael Burschik]

(use-modules (oop goops))

(define-class <test-class> (<class>)
  name)

(make <test-class>)



This makes guile 1.8.5 crash with a segmentation fault on Linux. I don't 
think it should.

Michael

Actually I confirm. The above code appears to work, but any further activity
makes guile segfault:


$ guile
guile> (use-modules (oop goops))

(define-class <test-class> (<class>)
 name)

(make <test-class>)guile> guile> (+ 3 4)
Segmentation fault
marijn@hakbak ~ $ + 3 4)


as you can see, guile did not even consume all the input

But it segfaults for me on linux. Gentoo here as well.
Both 1.8.6 and 1.8.4 behave similarly:

kjetil@ttleush ~ $ /usr/bin/guile
guile> (use-modules (oop goops))
guile> (define-class <test-class> (<class>) name)
guile> (make <test-class>)guile> guile> (+ 3 4)
Segmentation fault

Strange Cut-and-paste error above, but
it segfaults right after evaluating
"(make <test-class>)"

I also get this one from executing dmesg:

guile[10808]: segfault at 608 ip b7f2a2f3 sp bfcaab70 error 4 in libguile.so.17.1.2[b7ed7000+c9000]
